WOOD-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,048, dated February19, 1889.

Application filed January 30, 1888. Serial No. 262,396. (No model.)

.To all whom it may concern:

Be it known that we, ALFRED B. I-IUTOHIN- soN and ERNST F. AUTENRIETH,both of Brooklyn, (Green Point,) in the county of Kings and State of NewYork, have invented a new and useful Improvement in Wood-PlaningMachines, of which the following is a specification.

The invention will be hereinafter described, and particularly pointedout in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a portionof ainachine embodying our invention. Fig. 2 is a transverse sectionupon the plane indicated by the dotted line z 2, Fig. 1. Fig. 3 isatrausverse section of an upper roll-frame, whereby the two sections ofan upper feed-roll are supported upon the plane indicated by the dottedlines: :0,- Fig. 2.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the side frames of the machine, and B designates an uppercutter-head. The journals 1) of this cutter-head are fitted in boxes 1')upon a cutter-head frame, B, which has brackets or flanges 11 bearingupon the cutter-head stands A, which rise from the main frame A. Thecutter-head frame B may beadj usted upward and downward upon the standsA by any of the means usually employed for this purpose, and we have notshown such adjusting means, as our invention in no'wise relates thereto.The cutterhead B is driven by a belt, 19 from a pulley on the usualcounter-shaft, B which is at the front or feeding end of the machine.Upon the front side of the cutter-head B is a bar or mouth piece, Bwhich extends across parallel with the cutter-head and which isadjustable in the cutter-head frame B. Such adjustment may beaccomplished by means of screws 1)" Upon the opposite or rear side ofthe cutter-head B is a bar, B", which constitutes a chip-breaker andwhich is adjustable upward and downward. This chipbreaker is supportedfrom the cutter-head frame by means of arms or links I), which havecircular eye portions 0 embracing circular hubs concentric with thecutter-head bearings B. The ends of the chip-breaker are secured byscrew-and-slot connection to the arms or links I).

Behind the cutter-head B we have represented two pairs of feed-rolls,which are upon the opposite sides of standards A rising from the mainside frames, A. These standards A have in them slots (1, for a purposehereinafter described. The lower rolls, C, of the two pairs arejournaled in stationaryboxes cf, and the upper rolls, C, are eachcomposed of two sections, or, in shop parlance, are broken, as bestshown in Fig. 2. The sections of the upper rolls, C, are mounted inboxes 0 c and the boxes of each of said upper rolls are supported in anupper roll-frame, C ,which extends transversely of the machine, as bestshown in Fig. 2. The upper roll-frame, C has at opposite ends sockets oreyes 0 which fit rods 0 C at opposite sides of the machine.

The rods C at the side of the machine opposite to that which is shown inFig. 1 are simply smooth cylindric rods supported at their lower andupper ends in bearings or rests c, and which serve simply as guides mentof these screws is prevented by collars 0 upon them resting upon theirbearings 0 but when the upper roll and its upper rollframe, C arelifted, the corresponding screw C is lifted. Each upper roll-frame, C isconnected at opposite ends by rods d with arms d upon a rock-shaft, D orD. As here represented, both rock-shafts D and D are concentric, thelatter being tubular and journaled upon the former. The arms 61 of onerock-shaft extend in one direction to the rods cl, by which they areconnected with one upper roll-frame, and the arms cl of the other andare loaded by springs Zia rock-shaft extend in the opposite direction tocorresponding rods (7, whereby they are connected with the otherroll-frame, Consequently it will be understood that whenever eitherscrew is turned by a handle, c applied to its upper end both ends of theroll :t'rame C will be raised equally, because of their connection withthe one rock-shaft.

\Ve do not; claim as oi our invention the comlilination, with the upperrolls of two pairs, of the two concentric rock-shafts, one surroundingthe other, and which are connected by arms and rods, one with each ofthe upper companion section C may bear upon the roll-supports, as suchsubjectanatter is ineluded in the application of James F. elch, SerialNo. 2ti2,'l0t), tiled January 97, 1888.

The lower endsot' the screws (1' are prolonged downward below th eirbeari n and,

as here shown, have connected with them a l yoke, and (1 designates aweighted lever, which is t'ulcrumed at c, and which is hung by astirrup, upon the yoke This arrangement oi weights being applied to thescrews is, through the connection of each upper roll-frame, (.7 at itsopposite ends with one rock-shaft, distributed upon both ends of eachupper toll-frame, C

The boxes 0 0 in which the sections of each upper roll, (2, arejournalcd, have a limit-ed verticzll movement in theupperroll-frame, CEach of the outer boxes, 0", is arranged in a slideway, e, and hasbearing upon it a spring, 6, whichis in a cupshaped cavity, 6" in theroll-frame, and is here shown oli' india-rubber. Above the spring c isan adjlisting-screw, c, and by setting this screw (flownward the spring6' may be caused to act with greater force upon the box c'. The centeror inner boxes, 0 are supported in a slidcway, 0*, and are limited intheir upward movement by stop-bolts 0.

Above them is a s )ring, e'flwhich is arranged in a cu p-shaped cavity,c, in the upper rollframe, and which is controlled or adjusted by ascrew, c". here represented as a spiral spring of steel, is a t'olltnvcror plate, c and through a toggle-link, c, and a saddlepiece, e", theforce of the spring c is distrilnit'ed upon the two inner roll-Frameboxes, clwhich are at the adjacent inner ends of the sections of theupper roll, t", as shown in Fig. 2. The link or knuckle has rounded orknuckle-shaped bearings upon both the disk or follower e and thesaddle-piece c, and consequently the force of the spring 6 is appliedequally to both the adjacent boxes (5 and either box may rise to theextent permitted in the frame C without disturbing or causing the otherbox to rise. The movement which the boxes c e have in the upperroll-t'rame is very limited, and need be only about onequarter orthree-cighths of an inch. 'When the boxes 0 c are maintained in theirlmvermost position in the frame C it true that: the weights which areapplied to the roll-frame have no direct effect upon the boxes; but: thesprings e c with llelow the spring 6, which is panion section (.1,instead of being raised therewith, will bear upon the lumber of leastthickness, and will therefore feed it straight; through the machine;also, when two boards or pieces of slightly unequal. thickness are topin, the one roll-section C may rise by its contact with the thickerlumber, while the thinner board or lumber and feed it properly along.

Upon the lower rolls, (f, are pinionsfnvhieh are geared together by anintermediate wheel,

f, and upon one of the lower rolls, L, is also 7 a larger gear-wheel, fwhich is in gear with a driving-pinion,f which may be upon what isusually termed the pinion-shaft I oi the machine.

Inasmuch as the upper rolls, t", are broken, it is necessary to drivepositively the two sec tions of each roll. lVe therefore provide ashaft, F, intermediate between the two upper rolls, and which issupported in bearings f, extending inward from one of the upperroll-frames, O

The shaft h" is received in the slots a, formed in the standards A andconsequently it is free to rise and fall'with the upper roll-frames, CUpon each of the sections of each upper roll, 0, are pinions or wheelsf, both of which are in gear with corresponding pinions or wheels, f,upon theintermediate shaft, F, and consequently if to tary motion istransmitted to the shaft F the sections of both the upper rolls will beindividually driven therefrom.

Upon one of the lower rolls, (.1, at its end. opposite theconnecting-gears ff is a pinion,

,f", and upon a correspont'ling end of the intermediate shaft, F, is awheel or pinion,f Gearing with both said wheels f f is an ex pansiongear or wl1eel,f-", which is supported by swinging links f from theshaft F and from thc'lowcr roll, C, on which is the wheel Consequently,no matter what the rising or falling movements of the shaft F and theupper rolls, motion is always transmitted through the wheels/" f f tothe upper shaft, F, and thence to the upper rolls.

\Ve make no claim, broadly, to the arrange ment and construction of theexpansion-gear ing here shown to transmit motion to the upper roll or tothe wheel or shaft geared with the upper rolls of two adjacent pairs, assuch subject-matter lin'oadl y elaii'ned in the aforesaid application ofJames F. \Velch; but we limit our use of such expansion-gear to itscombination with upper rolls each composed of two sections and anintermediate shaft between the two upper rolls and which is geared withthe sections of each roll.

hat we claim as our invention, and desire to secure by Letters Patent,is-

l. The combination, with a lower feed-roll, journaled in stationarybearings, of an upper roll composed of two sections arranged end forend, an upper roll-frame in which both sections of the upper rolls arejournaled at each of their ends, said frame comprising sockets at theends thereof and made integral therewith, one of said sockets forming anut, two vertical rods, one at each side of the machine, and one ofwhich is a screw e11- gaging said nut, a crank for rotating said screwso as to bodily raise and lower the rollframe and the upperroll-sections journaled therein, journal-boxes for the upperroll-seetions supported wholly in said frame and capable of a limitedvertical movement therein, said journal-boxes being acted upon bysprings to press them downwardly in the frame, substantially asspecified.

2. The combination, with the lower roll, C, and the upper roll-sections,O, of the upper roll-frame, C the boxes for the roll-sections having alimited vertical movement in said frame, the springs 6, whereby theouter boxes are held down, and the springs e, and a sad dle whereby thetwo inner boxes are held down, substantially as herein described.

3. The combination, with two pairs of upper and lower rolls, the lowerrolls being journaled in stationary bearings, and the upper rolls beingeach composed of two sections, of an upper roll-frame for the sectionsof each roll, and boxes for the roll-sections having a limited verticalmovement in said frame, a shaft intermediate between the upper rolls andgeared with the two sections oi each upper roll, and journaled inbearings projecting from one of the roll-frames, gearing connecting thelower rolls of the two pairs, and expansion-gearing connecting one ofsaid lower ends thereof, one of said sockets forming a nut, two verticalrods, one upon each side of the machine, extending through said sockets,one of said rods being a screw and engaging a screw-thread in itscoacting socket, a crank whereby said screw-rod may be moved up and downin order to bodily raise and lower the frame and the upper feed-rollsection, a rockshaft having arms connected by rods with the ends of saidupper roll-frame, a weight applied to said rods, and boxes for the upperroll-section having a limited vertical movement in said frame, and whichare acted upon by springs to press them down in the frame, substantiallyas specified.
